description PROBLEM TO BE SOLVED: To provide a powder supply device 1 capable of stably supplying a predetermined quantity of powder P to a storage bag B even after air-blowing a deaeration net 5.SOLUTION: A control part 60 of a powder supply device 1 includes a deaeration control part 62 and a forced feeding control part 63. The deaeration control part 62 controls deaeration of air from a deaeration space S intermittently with a constant timing so as to control a supply amount of powder P supplied per one storage bag body B from an exhaust port 22 of an inner cylinder 2. The forced feeding control part 63 controls forced feeding of air to the deaeration space S and forced feeding stop of air repeatedly so as to get to a forced feeding time T1 and a forced feeding stop time T2 of air longer than the forced feeding time T1.SELECTED DRAWING: Figure 1 【課題】脱気網5をエアブローした後も、所定量の粉末Pを収容袋体Bに安定して供給することができる粉末供給装置1を提供する。【解決手段】粉末供給装置1の制御部60は、脱気制御部62と、圧送制御部63とを備えている。脱気制御部62は、内筒2の排出口22から1つの収容袋体Bあたりに供給される粉末Pの供給量を制御するように、脱気空間Sからのエアの脱気を、一定タイミングで断続的に制御する。圧送制御部63は、エアの圧送時間T1と、圧送時間T1よりも長いエアの圧送停止時間T2となるように、脱気空間Sへのエアの圧送とエアの圧送停止とを繰り返し制御する。【選択図】図1
